Tetra Tech to Provide EPC Services to US Wind Energy Projects

Tetra Tech, a provider of consulting, engineering and technical services, has been awarded two engineering, procurement, and construction projects and one balance-of-plant construction project for wind farms in the US.

In aggregate, the wind farms will generate 218.2MW of clean energy, enough to power more than 55,000 homes. The combined value of the three awards is $69 million.

For the Oklahoma Gas & Electric Company, Tetra Tech will provide engineering, procurement, and construction (EPC) services for the OU Spirit wind farm, which is expected to consist of 44 Siemens 2.3MW turbines to be installed near Woodward, Oklahoma.

Tetra Tech was also awarded a project to provide balance-of-plant (BOP) services for the High Sheldon wind farm in Wyoming County, New York. This Invenergy project will have a maximum electrical generating capacity of 112.5MW. Tetra Tech is constructing roads and foundations to support the installation of 75 wind turbines on predominantly active agricultural lands.

Finally, Tetra Tech will provide EPC services for Kodiak Electric Association's Pillar Mountain wind project on the Kodiak Island, Alaska. This project includes the installation of three General Electric turbines capable of generating 4.5MW of power. Work on the project began in late May 2008 and is expected to be complete by July 2009.
